Even in the island paradise world of “Hawaii Five-O,” the plague of “too much information” is problematic, and the omnipresence of social media takes an ugly twist on the April 29 22nd episode for Season 6, “I’ike Ke Ao” (For the World To Know). A quiet night of babysitting turns into a harrowing ordeal, thanks to criminal captor who really knows the joys of hacking, and wicked, perverted pleasures. Steve McGarrett (Alex O’Loughlin) officially commissions a secondhand HPD ship to sail Kamekona (Taylor Wily), Flippa (Shawn Mokuahi Garnett) and Dr. Max Bergman (Masi Oka) around for a “booze cruise,” but they miss the boat on being prepared. At least the team ends up with their crook in custody, and a definite upgrade in travel accommodations.

Addison Wells (Cassi Thompson) has a easy and steady gig as babysitter for the Hillers (Jeremy Gilbert and Wendy Callo), who have a precious baby daughter, a beautiful home and very good pay for a few hours’ care. She’s transfixed into texting and video chatting on the side, until she thinks she hears the baby’s cry. Things get creepier and creepier as she traces strange sounds to a dark room with only her cell phone, and a predator lying in wait. The Hillers return home, finding a strange man, posing as security, and holding the strangest baby doll to pass for a real baby since the incredulous scenes of American Sniper. Their paid caretaker is nowhere to be found, and dad is quickly zapped by a stun gun. Meanwhile, the three amigos out for their day of frolic are sent off with the blessing of Lt. Commander McGarrett, even if the bottle he broke on the bow isn’t big enough to bless a fishbowl. This case is right up . Jerry Ortega’s (Jorge Garcia) alley, and it doesn’t take long to discover that with everything being “smartly” connected in the Hiller home, everything in the system had been hacked, from baby monitors, to thermostats, to every bit of information on the computer that Addison was using. Her schedule was an open book. She was the target.

Trace first leads to a Jeremy F., but the photo is ripped off from a rugby player. The technical maze gets a little daunting even for Jerry, but Kono (Grace Park) knows just who to call, Adam a.k.a. “Toast” Charles (Martin Starr), who hasn’t met any spyware that he cannot break. Steve intercepts him from his plane, on the way to chicken and waffles, and commissions him for the case. Danny (Scott Caan) is torn between admiration and despising the genius, and inventor of “Poopy Birds,” the videogame that captivates his kids, and costs him. Toast helps the team to track e-mails, which lead to a nondescript office building , and Howard Mintz (Scott Paul Robertson), who was an earlier would-be suitor for Addison, but he insists that he had nothing to do with her kidnapping or being missing. The cyber stalker also installed spyware on computers of at least 12 other women, so Addison wasn’t the only one, now shown bound and tied. “Cherry bomb” spyware that infects every program and keystroke was used on Addison, and Toast’s old friends are not willing to help, until Jerry puts the police hammer down. He gets a little more respect because his “nerd credentials are in order.” The team investigates the home of Jacob Holms (Scott Michael Campbell) , and knows they have their man. Strands of electrical connection lead to the computer screen of another victim, Jason Putnam (Timothy Antoine Cullais), splattered with blood , confessing his crime of embezzlement, and himself shot in the head on the floor. “Hawaii Five-O” then realize that Addison’s taker targeted her because she had a circle of people who loved her through everything, but she also had a dark secret.

The boys on the boat are not having fun, nor are they traveling far, and Max and Kamekona concur that the boat has no gas, and no charged battery. They have no means to make a mayday call. Flippa finds a working flare gun, and shoots it up into the sail, setting it on fire. A series of other mishaps, paired with combined inebriation, leave the trio washed up on a far island. And the rest of their friends plead with them to stay. Ridiculous arguments break out, some even worthy of “MxDanno” status, over why some humans make more preferable meals, and being “better than zombies.” While Addison’s keeper wants more, the “Toast” philosophy is taking it easy together. He purposely “trumps” off the captor, hoping to get tipped off with more information. It is revealed that Addison’s secret is that she killed a man as a young teenager, even before her recent texting. Refusing to let her go, but leaving “some mercy” on the table, from his gun, her captor taunts and torments her. The trace and trap method starts to work.

Grabbing the gun, Addison misses her mark trying to kill her tormentor, but the bullet grazes his head enough to attempt a getaway. The young target and her exacerbating captor go at it in battle . They scuffle over a piece of rebar stuck in his abdomen. In a gruesome scene, he pulls it from himself, and starts to stab it into Addison, but the sound of “Hawaii Five-O” making their entrance detracts him. Holm is taken under arrest , and Kono assures Addison of safety. Back on the island, everyone is singing around the camp fire, and sharing stories of their personal biggest regrets. They say “night-night” as though it were an episode of The Waltons, with all the children gone. When Kamekona tries to catch some sleep, he sees what he thinks are flares from a ship, ready to rescue them, and th en sees them as firecrackers. Tourists come along to remind them all that the hotel on the island has food.

Steve and “Toast” take it first-class to chicken and waffles, while Danny takes a snooze on Jerry’s shoulder in coach. Kidnapping has been a recurring theme all season, and it pops up again with next week’s episode, involving the niece of Chin Ho Kelly, so keep watching. There’s just two more episodes to go for the season.
